APPARATUS FOR MANUFACTURING OXID E$ OFQMETALS.

SPECIFICATION forming part of Letters Patent No. 468,216, dated February 2, 1892. Application-filed February 18, 1891- Serial No.381,936. (No model.) A

To' all whom it may concern:

ides of Metals, of which the followingisafull,

clear, and exact description.

The object of the invention is to provide a new and improved apparatus for manufacturing oxides from readily-oxidizable metals, and which is simple and durable in construction, efiective inoperation, and forms the oxides at a very low cost.

The invention consists of a nozzle provided with a disk extending into a spraying-recess and havinga central aperture for the passage of the molten metal to the top of the said disk and an air-blast connection leading to the said recess under the said disk.

The invention also consists in certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is an enlarged sectional side elevation of the nozzle on the line w w of Fig. 3. Fig. 3 is a plan view of the same, and Fig. 4 is an inverted sectional plan view of the same on the line 'y y of Fig. 2.

The improved apparatus is provided with a vertically'arranged. oxidizing-chamber A, preferably made in the shape of an inverted truncated cone and provided at its lower end with the cylindrical part B, resting on a ringshaped bed-plate C, supported on a wall D,

forming a space E, connected with retorts or furnaces generating hot air, which can pass into the said space E; In the lower end of the cylindrical part Bis held the nozzle F, provided with a plate G, resting on an inward projection of the bed-plate O and provided on its under side with a circular ofiset H, on

of the plate G, and in the said disk and the said plate is formed a passage Q, connected with a pipe R, provided with a stop-cock R and leading to the bottom of the vessel S, contairing a suitable molten metal, preferably lea The vessel S is arranged somewhat above the disk 0, so that by opening the stop-cock R and the passage Q onto the top of the disk 0 and there spreads out to the edge of the ing upward through" the space P.

In the plates G and N are formed registering openings T, connecting the space E with the cylindrical part. B, so that hot air can pass up into the oxidizing-chamber A.

R the metal readily flows through the pipe disk to be taken up by the hot-air blast pass- The operation is as follows: When the hotair blast passes under pressure through the pipe I and the openings J into the sprayingrecess K and the molten metal is permitted to flow to the top of the disk 0 at the same time,

then the air-blast in passing through the space P engages the outer edge of the molten metal spread on the disk 0, thereby carryingfupward small particles of the molten metal, which is thus brought to a finely-comminuted condition, inwhich it is readily oxidized and carried off by the force of the blast to the condensing-chamber connected with the upper end of'the oxidizing-chamber. The hot blast passing intothe cylindrical part B and the oxidizing-chamber A causes a circulation of air through the retorts or furnaces connected with the space E, so'that the hot air is drawn from the said space E and openings'l into the oxidizing-chamber O at or near its lower end, thus assisting in maintaining the required heat to perfectly oxidize the finelycomminuted metal. In this manner an aircompressoris not: required for forcing the necessary amount of air into the oxidizingchamber A, and only such a force of hot-air blast is required as is necessary to spray the 'inditen lead on top o-ftheldisk o and to force Y the; sprayechmetai' 'up into I. the oxidizingchamber.
